[0036] The cylinder mouth (2) remains exposed over the front pillar frontal side (3) and in the same plane to it, in the cylinder mouth (2) remains exposed a piston extreme (5) mounted inside the cylinder (2) in slipping form and in opposition to elastic means conformed by a spring (6) disposed between the piston( 5) and the cylinder (2) bottom the piston is hollowed and in the transversal sector presents a rectangular oblong form with minor sides in circling arc.

[0037] Inside the piston (5) remains a mounted plaquette (7) fixed to a rectangular form rod (8) coaxil to the piston (5) and the cylinder (2) extending the rod (8) through the piston (5) and cylinder (2) bottom (5′-2) to remain confronted by its rear extreme to an activate medium (9) of electro-pneumatic (10) valves circuit constituent part (11) to suck and supply pressure air. The rod (8) plaquette (7) carrier is the same than the piston (5) permanently asked by a second spring (12) both springs (6 and 12) are coaxils and present extremes with support over the cylinder (2′) bottom being a spring (12) extreme with support over a rod (8) prominence (8′).

[0038] The front pillar (3) presents a groove (13) in its sideway (3′) face (see FIGS. 1 and 2) who is extended through the pillar body (3) in order to couple tangentially with an annular groove (14) formed by a lengthen rabbet (15) from piston (5) extreme, and the cylinder (2) inside surface (2′) this pillar (3) groove (13) presents a wide mouth (13′) for strap or strip admitance (16) supplied by a dragging pair of rollers (17-17′) the strap or strip (16) is plastic laminar material or metallic laminar and goes into the apparatus by dragging rollers (17-17′) actioned by a motor (m) represented in FIG. 1.

[0039] The front pillar (3) groove (13) is at an intermission point between its mouth (13′) and the couple point with the annular groove (14) interrupted by a guide groove (18) transversal and perpendicular to it and to front pillar (3) and in parallel axe to the cylinder (2) in this small cylinder (19) remains a mounted piston (20) who possess a lengthen cutter (21) lodged in the guide groove (18) being the piston (20) inside the small cylinder (19) opposed to a spring (22) and the small cylinder (19) in communication with the refered circuit which supplies pressure air (11), the front pillar (3) presents in the same plane to the cylinder (2) a vertical lengthen middle plane and under the cylinder a prismatic and rectangular lodge (23) who upperly is in communication with an aperture (23′) with the annular groove (14) formed by the piston (5) and the cylinder (2) through an overly aperture (34) in the front pillar (3).

[0040] To the welding device perfomance (31) and the dragging rollers (17-17′) actioned by the motor (m) electric energy is utilized. To actioned the piston (5) sequencially, the piston (20) with the cutter (21) and the prongs (25) carrier piece (25) pressure air is utilized, supplied by the circuit (11) commanded by an activated medium (9) of electro valves (10) which in time is operable by the rod (8) plaquette carrier (7) like can be see later. In all cases movementes are synchronized through the use of micro-switch program functions conventionally knowed in the practice, which allows the medium secuential action to achieve the sealer formation to fasten legs automatically. The apparatus perfomance is as follows: the strap or strip (16) dragging by the rollers (17-17′) goes into through the groove (13) mouth (13′) to flow out in the annular groove (14) formed by the piston (5) rebate (15) and the cylinder (2) internal surface (2′) the tape (16) slides tangentially in the annular groove (14) covering perimetrally its 360 degrees surpassing almost a 10% the free extreme of the annular groove perimeter (14) being the last in communication with the lodging (23) opening (23′) of rectangular form, placed under the cylinder (2) in this way the apparatus remains charged and/or ready to automatically seal both poultry legs.

[0041] Right after the poultry is taken by the thighs the legs are putting into the piston (5) exerting a pressure on the plaquette (7) whose rod (8) pressure the actioner (9), and actioned the pneumatic electro-valve (10) opposing the spring (12) producing in the cylinder an air sucking (2) through the connector (H) to shrink the piston (5) opposing the spring (6) in this way the ring formed by the tape (16) remains free or loose inside the cylinder (2) sorrounding the poultry leg.

[0042] In synchronized form with this motion, the electro valves (10) who feeds circuit (11) connectors (C-G) are activated (10), one of them allows to feed the small cylinder (19) with pressure air which push the piston (20) who carries the cutter (21) whose transversal guide (18) displacing to groove (13) produces the tape horizontal cut (16) (FIG. 17) another electro-valves through a connector (C) go into the lodge (23) pressure air pushing the prongs (25) carrier piece (24) who nailed themselves in the tape (16) superpose areas through the piston (5) groove (26) this operation is performed before the piston displacement (5).

[0043] When the last is going back, the piece (24) movement allows the prongs (25) dragging and folding the ring lower part, formed by the tape (16) through the poultry legs, opposing the folded under part of the tape ring formed with the upper part of the aforesaid in order to contact both parts of the tape ring against the welding device (31) and produce the grasp of both parts of the ring, forming respectivally around each leg, rings or clamps united integrally between them.

[0044] In this way a double ring of plastic material or metallic laminar form a seal for both legs delimited (see FIG. 8) by an upper part lightly curved which is extended sideway in curved spans in circle arcs to finish centrally in opposed right spans and contents in slightly inclined planes, which are united, in bent right angle spans and yuxtapose to the under surface of upper span through welding lines. In its first perfomance the apparatus purpouse is to do and to place automatic and simultaneously an inviolable sealer or faster in both sloughty poultry legs.

[0045] FIGS. 9 to 19 represent a second performing invention whose purpouse is to seal automatically only one of the sloughty poultry legs, so is to seal only one of the legs starting from a plastic laminar or metallic laminar material strap or strip, the legs can be separated or not from the poultry body over the tibia area.

[0046] To conclude in this performing the apparatus put on an inviolable identificatory seal in any poultry leg which can include printed labels with important datum for the consumer (slaughter date, weight, producer name, etc) this sealer sorrounds the leg tibia remaining closed or blocked between the thigh and the stump or the kneepan.

[0047] According can be judge on FIG. 9 and 10 this performing apparatus is constituted by a frame (1 a) and a cylinder (2 a) fixedly supported in the frame (1 a) in an horizontal form remaining open one of the bases, the front at same level with the frame (1 a) front pillar (3 a) outer surface and with its rear extreme portion wich support over the rear pillar (4 a), the cylinder (2 a) presents upperly in its wall starting from the open pillar base an opening (35) who lengthly extends to an intermession point of its shirt and possess a determined angular breadth, this cylinder (2) lodges inside a partially hollow piston (5 a) who is represented in FIG. 15 possess an upper vacuum (36) which is extended between an extreme ringed and fronted portion (37) and the rear (37′) close extreme portion to delimite upperly in the aforesaid piston (5 a) opening in, correspondence with the cylinder (2 a) opening (35) when the apparatus is out of order state, the underly piston (5 a) possess a wall (38) portion that conforms an under broader sideway, and presents an upper surface (38) in a floor way who does a lower support to the leg, complemented with a front bevel (38″) to allow the input of the last (like further on can be see) remainig delimited by the piston (5 a) starting from its extreme ringed (37) portion. A vacuum transversal section with circle segmented form.

[0048] This piston (5 a) possess underly and starting from its front (37) ringed extreme a flat (39) transversal rebate, confronted to a vertical (23 a) lodge rectangular prismatic of the frame (1 a) front pillar (3 a). This lodge (23 a) incorporate a strap or strip (16 a) nailing device constitute by a plaquette (24 a) of similar section who presents prongs (25 a) in its upper extreme, and too in its lower extreme connected by a rod (40) to a pneumatic (41) device.

[0049] The plaquette (24 a) upper extreme with the prongs (25 a) remains in vertical coincidence with the piston (5 a) flat (39) rebate, presenting this flat (39) rebate a groove (42) in its middle part holding over the simetric vertical plane of the piston (5 a) for prongs (25 a) transitory confinement (like further on can be see) the plaquette (24 a) presents laterally a concavity (24′) in order to avoid the contact with the poultry leg to be seal like is indicated in FIG. 17 with all details.

[0050] The piston (5 a) and then inside cylinder (2 a) surface delimite an annular (14 a) groove who couples tangentially in the vertical lodge outlet (23 a) with the cylinder (2 a), with the frame (1 a) pillar (3 a) groove (13 a) which like in the first performing allows the strap or strip go in through the pair of rollers (17 a) and (17′a) in intermitent form to conform the seal in the cylinder (2 a) front extreme and in a diametrally opposed form from the plaquette (24 a) with prongs (25 a) to the vertical (23 a) lodging outlet is fixedly mounted to a tape (16 a) welding (42) device that built in a sucker (43) of the last, with sucker and lodging (43′) grooves for the prongs (25 a).

[0051] In opposed form to the front extreme open piston (5 a) and in form lightly spaced of the last and the cylinder (2 a), can be available a plaquette (7 a) to support the poultry stump extreme. This plaquette (7 a) presents a perimetral conformation similar and hardly smaller than the free transversal section of piston (5 a) segmental circle to allow a free introduction inside the last.

[0052] The plaquette (7 a) is provided with a heel (44) to place and support the leg to be sealed who potrude and is displaced in sideway plaquette (7 a).

[0053] The last is supported in a rod (45) extreme who is projected inside the piston (5 a) and the cylinder (2 a) in eccentric form to them and with respect to a rod (46) refered concentrally to the piston (5 a) the rods (45) are (46) parallel between them, crossing the cylinder (2 a) butt (2 b) and are connected respectively to edges (47) and pneumatic devices (48) and like the pneumatic (41) device are connected and feeded by a supplier pressure circle no represented.

[0054] At last the annular groove (14 a) in coincidence with the vertical (23 a) lodging outlet presents an edge (47) at 45 degrees in a cutter way of the strap or strip (16 a) represented in plant in FIG. 16 which allows to cut the last before forming the seal in the poultry leg tibia.

[0055] The apparatus function to seal automatically one of the poultry legs at is second performing, is as follow, the starting sealing process starts when the rollers operating through an electric motor, (17 a) and (17 a′) who tractioned intermittently the strap or strip, (16 a) and sideway to the frame (1 a) through the front pillar (3 a) groove (13 a) to do outlet in the annular (14 a) passage over the cutter formed by the rim (47) and over the plaquette (24 a) prongs (25 a). The free extreme of the tape (16 a) is addresed inside the annular groove (14 a) along a perimetral arc of approximately 200 degrees so its free extreme surpass the welding device (42) and the sucker (43) giving to the strap or strip (16 a) a semi ring form, moment in which the rollers (17 a) and (17 a′) are stopped.

[0056] Next step is to proceed to enter the poultry leg (P) to be sealed supporting the stump against the plaquette (7 a) and the sideway against the heel (44) to allow the plaquette (24 a) with the prongs (25 a) the leg placement and the aforesaid pressure over the plaquette (7 a) produce the plaquette displacement and its entry inside the piston (5 a) with the simultaneous rod (45) recess solidary to plaquette (7 a) that operate a pneumatic device sensor (47) connected to the rod (45) which allows to start the sealer remaining operations.

[0057] The pneumatic device (47) operating sensor habilitate the sucker (43) connecting its channels (43′) and by sucking retains the strap or strip (16 a) upper extreme portion which surpass the welding device (42) in the annular groove (14 a) and at the same time is operated the strap or strip (16 a) nailing device whose plaquette (24 a) with the prongs (25 a) is upward displaced by the pneumatic device (41) addresing the piston (5 a) this plaquette motion (24 a) defines the prongs (25 a) strap or strip (16 a) and the aforesaid contact or scuff against the edge (47) in a cutter way, producing a cut and a set aside with respect to the tape supplied by the rollers (17 a) and (17 a′). Simultaneously with this operation the plaquette (24 a) does top against the piston (5 a) transversal plane rebate (39), and the prongs (25 a) are retained in the cutted strap or strip (16) rear extreme.

[0058] The plaquette (24 a) with the prongs (25 a) is commanded by the pneumatic device (41) who possess two electro valves, one of counterpressure to produce a plaquette (24 a) against the low intensity piston (5 a), and the other to lift the plaquette (24 a) when the piston (5 a) is totally retired inside the cylinder (2 a) once the plaquette (24 a) is retained against the piston (5 a) with its prongs (25 a) retains the cutted strap or strip (16 a) operated by the pneumatic device (48) who drags the rod (46) and therefore the piston (5 a) uncoupling the groove (42) related to the plaquette (24 a) prongs (25 a), simultaneously the pneumatic (41) device electro-valve allows to impel or lift the plaquette (24 a) with the prongs (25 a) to its extreme and the rear extreme tape (16 a) impacting against the welding device (42) and holding the rear strap or strip (16 a) extreme contacting the free extreme retained by he sucker (43) all this happens during half second for its mutual union and the sealer ring formation around the leg tibia. The plaquette (24 a) sideway concavity (24 a) prevents any friction with the poultry leg, besides this plaquette (24 a) remains ahead the heel (44) during the sealing without affecting or harming the poultry leg.

[0059] The piston (5 a) upper vacuum (36) puts away the plaquette (7 a) with the stump leg when the plaquette with the prongs (25 a) is lifting, retaining the tape (16 a) allowing the aforesaid vacuum (36) an upper stump motion or play for a free leg sealing.
